TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 477,032, dated June 14,1892..

Application led September 21, 1891. Serial No. 406.339. (No model.) l

To all whom t may concern:

Be it known that I, HENRY VEBER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Ventilator-Openers; andI do hereby declare the following to be a full, clear, andY exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a novel construetion in devices for openingwindows or ventilators, the object being to provide a device of thischaracter of simple and durable construction and that can be easily andquickly operated. V

The invention consists in the features of construction and combinationsof parts hereinafter fully described and specifically claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is avertical cross-section of a building provided with a ventilatorconstructed in accordance with my invention, and Fig. 2 is a verticallongitudinal section of the same.

Referring to said drawings, A indicates a building, and B the roofthereof, having the skylights or ventilators 1 and 2 on the inclinedsides thereof. The ventilators l and 2 are hinged, respectively, alongtheir upper and lower edges, as shown. It is obvious that any number ofventilators can be used, and for operating the same a rock-shaft 3 issupported in suitable bearings on the end walls of the buildings andextend longitudinally within the same. Adjacent each pair of ventilators1 and 2 said shaft 3 is provided with two crank-arms 4 and 5, rigidlysecured to said shaft. Links 6 and 7 are pivoted at one end to the outerends of said crank-arms 4 and 5 and at their other ends to the free orswinging edge of said ventilators. It will be plainly seen that when theshaft 8 1s turned it will serve to open or close the ventilators in anobvious manner. For turning said shaft a couple of oppositely-disposedradial arms 8 and 9 are rigidly secured thereto conviently at the endthereof, as shown, and a sprocket-chain or other equivalent connec tion10 is secured at its ends to said arms and 9 and passes around asprocket-Wheel l1 o`r equivalent device rigidly mounted upon a shortshaft 12, supported in suitable bearings on the end wall of thebuilding. A crank 13 is secured to said shaft 12, and by means of whichsaid shaft. is turned. A disk 14 is rigidly secured to said shaft 12 andis provided with a series of perforations l5, by means of which it canbe secured by a pin 16, passing through a bracket 19 and engaging one ofsaid perforations. It will be noted that when the crank 13 is turned inthe direct-ion shown by the arrow the ventilators Will be lifted to theposition shown in dotted lines in an obvious 1nanner,-and that afterbeing lifted they can be held in an elevated position by the pin 16being slipped. into one of the perforations 15. Vhen it is desired toclose said ventilators, the pin is removed to allow the shaft andsprocket-wheel to turn. I have also provided a counterbalancing-weight17 upon an arm 18, secured to said shaft 3. In opening and closing theventilators this weight 17 counterbalances their weight, so that theycan he operated with greater ease. lVhen said ventilators are closed,the weight 17 stands a little to one side of the center of the shaft 3,`so that in opening the ventilators at first the Weight has to be liftedand then carried to the other side of the. center of the shaft. It willthus be seen that when the ventilators are closed thecounterbalance-weight 17 serves to hold them close against the action ofgusts of Winds or storms which might open them.

It will be noted that my invention can be usedv for operating a singleventilator or any number of ventilators, as may be found convenient.

I claim as my inventionl. The combination, substantially as hereinbeforeset forth, with the hinged ventilators of a building, of arock-shaftsupported in bearings on said building, crank-arinst and 5 upon saidshaft, links G and 7, connected with said crank-arms 4 and 5 and withsaid venti` lators, arms 8 and 9, secured to said shaft, gearconnections between said arms 8 and 9 anda revoluble shaft l2, aperforated disk 14 upon said shaft 12, a bracket 19, having a pin 16 forengagement with said disk, and a crank 13 :for turning said shaft- 12',substantially as described.

IOO

2. The combination, substantially its herenbefore set forth, with ahinged ventilator of a building, of a rock-shaft supported in bearingson said building, a crank-arm upon said shaft, a. link connected withsaid crank-arm and With said ventilator, a counterbalance- Weight uponan arm projecting from said shaft for oounteracting the Weight of saidventilators, said counterbziizince-weight being.,r so 1ocztted that Whenthe Ventilator is closed said l weight will stand to one side of thecenter of the shaft and upon the opposite side thereof in which it movesin opening and closing said ventilators, and devices for turning saidShaft, substantially as described.

In testimony whereof I affix mysignature in presence of two witnesses.

HENRY WEBER.
